295 Sect et NOFORN Chapter 6 these aircraft were hastily flown to Edwards Air Force Base. From this point on, the Air Force versions of the OXCART were based at Edwards and provided a diversion so that the faster and higher flying A- l 2s at the Nevada site could continue testing out of the public eye. The President's announcement did not mention the CIA's in volvement in the project, which remained classified, but keeping the Agency's extensive role in the OXCART a secret was not an easy task. The first step had been to separate the Air Force's versions of the A-12 from the Agency's by moving the Air Force aircraft to California. Next, those firms that were to be given the new technology had to be briefed on the program and agree to abide by the same secrecy agree ments then in force with Lockheed. Moreover, everyone witting of OXCART (including those no longer associated with the program, such as Allen Dulles, Richard Bissell, and General Cabell) had been briefed about the impending Presidential announcement, so that they would not think that the need for secrecy about OXCART had ended .....

Deciding that renaming the aircraft was easier than correcting President Johnson. the Air Force invented a new category "strategic reconnaissance"-to explain the SR-7l's designation. ADDITIONAL PROBLEMS DURING FINAL TESTING The first A-12 crash occurred on 24 May 1963, when a detachment pilot, realizing the airspeed indication was confusing and erroneous, decided to eject. The pilot was unhurt, but the plane was destroyed when it crashed near Wendover, Utah. A cover story for the press de scribed the plane as an F-105. All A-l 2s were grounded for a week while the accident was investigated. The malfunction was found to be caused by ice that had plugged up a pitot-static tube used to determine . d ~5 atrspee . • ..
